Many online casinos give bonuses to new customers when they make the first deposit. To protect the casino’s money, there is a minimum amount of money that the gambler has to wager to make a withdrawal. This prevents the gambler from immediately withdrawing the bonus after issue. For example, a casino offering a 100% deposit bonus means that as a gambler, my deposit is doubled. That is a deposit 100 NZD becomes 200 NZD, 200 NZD becomes 400 NZD and so on. If the wagering requirement is 50 times the bonus plus the deposit, I will have to bet a minimum of 200×50 NZD to make a withdrawal.
